or HARRIS COUNTY, TEXAS WELL PLNGER Application filed January 3, 1931, Seri-a1 No. 506,472. VRervva rebr'uarya?, 1933i;

My invention relates to wellplungers and has as its principal object'the provision of a well plunger wherein the various` parts of the pump and rigging are connected together by screw threads and prevented from becoming loosened or detached.

The present application is a division in part of my copending application, VSerial No. 429,189, filed February 17, 1930.

It is an object lofthepresent invention to provide a well plunger having means for causingthe liquid passing therethrough to exert a torque upon the threadedly connected 4parts of the pump and pump rigging so as `to keep the connections tight and prevent them from` Working loose while in operation. if Other objects will become apparent during the course of the following detailed d`escription, when taken in conjunctionl with the accompanying drawing which forms a' part of this specification, and inwhich;

Figure 1 is a longitudinal sectionof 'a por-y tion of a well plunger, .employing vmy invention; 1 L -2 Fig. 2 is a horizontal section taken onthe i line 2-2 of Fig. 1;

' line 4 4 of Fig..3; and

Fig. 3 is alongitudinal section of a portion of a well plunger illustrating a modi-l lied form of the invention;

Fig. 4 is a horizontal sectio'ntalrenon the Fig. 5 is a' view in elevation of my pum and a portionof Vthe rigging therefor.

Referring now to the drawing in detail and to Figs. 1 and 2 in particular, 5 indi Y cates the working barrel in ywhich the pump plunger 6 is reciprocated by means of a con# ventional rigging including a plurality of threadedly connected rods 6a. The plunger' 6 is made up of a plurality of threadedly `connected sections, the upper one'of which g is tlireadedly. connected with the lowermost pump rod.

The plunger Gaincludes a verticallye'X- tending central oil .pipe or conduitf? lwhich has itslower end threadedly engaged with the upper end of a cylinder 8 which may have the bore9 thereof slightly enlarged belowy the connection with the pipe 7. Suit-` able wiping `orpolishi-ng are provid'ed around thepipe 7k and bear against the inner surface of the barrel 5. f

-,A'spiral blade 11 ismounted inthefcyline` Vder t3. Thisspiral'blade 11`eXtends 'longitudinally of the cylinder and parallelwith.

the vside Vwalls thereof. Therouter edgeof the spirali is ,fin contact with the cylinder as it iiows upwardly through vthe, vcylinder*` incident to a Vdownward strole offthe plunger. This arrangement permits the use of a comparatively long spiral without Volostructing the'flow of oil through the cylin- -I f Y' Lerach n der and yet the liquid striking the under surface; 35 exerts sufficient torque as to maintain the various threadedconnections .of the' Y pump plunger andjrods in tight engagement.

The usual standing valve l4is'shown as Vbeing in engagementy withtlielifter152alf though it will bel understood that the valve 14 will, during the operation of lthepump,

be seated yat the bottom of the working bar Y rel Aand out of engagementfwith thepump plunger. The valve lifter 15 maybe threadedly engaged with thellower end of the cylinder 8 andl is provided with Suitable oil passages 16 through which the oil passes into the cylinder ,and thence out through V'pipe 7 to the next section of the.V pump plunger.-

Referring now to Figs. 3 and 4, which il i lustrate a modified form of the invention,

the working barrel has a pump plunger 1'? working therein, the pump plunger` 17 e being operated as usual byia rigging includ-k ing'pump rods 6a. Asin the case Zof the form of the invention shownin Figs. 1 andk 2, the plunger includes ,a e plurality of threadedly connected 'sections having a central vertical oil conduit extending'- therethrough and including the pipelSwhich has its lower end threadedly 'connected `to vthe upper end ofY acylinder 19, the upper end receive theen'd'ofsaid pipe.V l.

`ofthe bore 0f the Cylinde beitg'reduced to A baffle 20 of substantially spiral form isk mounted Within the bore of the cylinder 19. This spiral baffle is in the form of a twisted blade and is formed from a flat plate of steel or the like equal in Width to the diameter of the boreV ot the cylinder 19. The baiile or blade 20 is secured Within the cylinder by means of spot Welds 2l or in any other suitable vmannerl The blade 20 is twistedrin a direction so that oil passingup- Ward through the cylinder 19 will strike. the under face 22 ofthe spiral and exert euiiicient torque to maintain the threaded connections of the pump and pump rods in tight engagement.

The puller 23 for the standing valve (not shown) is no part of the present invention, but forms the subject matter of another application.

It Will thus be seen'that I have provided an extremely simple devicey for maintaining` the pump parts and rods in tight engagement and one in which there are no parts which can possibly get `out of order. Also by changing the pitch of the spirals, the twisting force exerted on the plunger and rodsmay be readily regulated.

Although a preferred embodiment of the invention has been shown and described, it

will be understood that various changes in the details of construction may be made Without departing from the spirit of kthe invention as defined by the appended claims.

I claim:

l. In combination iwith a plurality of threadedly connected pump rods and a pump plunger operated Athereby and hara longitudinal fluid conduit. therethrough; means Within said conduit for eX erting a torque on said plunger and rods incident to the passage of luid ltherethrough, said means comprising a baiile twisted to Jorm a spiral blade mounted Within the conduit of said plunger said blade having the opposite edgesA thereoi secured to the walls of the conduit.

2. ln Combination With a plurality ot threadedly connected pump reds and a pump plunger operated thereby and having a longitudinal fluidA conduit there-- through; the conduit including a cylindr connecte-l to the plunger means `within said conduit for exerting a torque on said plung-A 'er and rods incident to the passage oi liuid therethrough, said means comprising a baiile of substantially spiral forni mounted in said cylinder whereby to maintain the threaded connections of said rods and pump in tight engagement, the width ot the baliie throughout its length being substantially the same as the inner diameter ol the cyl inder.

3. in combination with plurality ol threadedly connected pump rods and a pump plunger Voperated 'thereby and having a longitudinal Vfluid conduit therethrough, a cylinder connecterL to ,the plung er in communication with the conduit and having a greater internal diameter than said. conduit, a spiral blade. secured to Sie wall of the cylinder and extending substantially 'the full length of said cylindr for exerting a torque on the plunger and rods incident to they passage of fluid thereto in order to maintain the threaded connectionev of said rods and pump in tight engagement.
